Xilinx's UltraScale+ FPGA technology
Integration into Fujitsu's 5G O-RAN radio devices
The first 5G greenfield network in the US is set to be built.


This standardizes the fronthaul interface connecting the radio units (RUs) and distributed units (DUs) required for implementing O-RAN (Open Radio Access Network) base station equipment. This enables interoperability between RUs and DUs from different manufacturers.

Xilinx announced on the 8th that it will provide its "UltraScale+" FPGA technology to Fujitsu's O-RAN 5G O-RU (O-RAN Radio Unit). The Fujitsu O-RU will be deployed in the first O-RAN-compliant 5G greenfield (6GHz unlicensed band) network in the United States. Fujitsu is currently evaluating Xilinx's RFSoC technology in preparation for additional field deployments.

Fujitsu O-RU is suitable for applications that leverage the wide spectrum and multi-band capabilities of 5G O-RAN networks. Xilinx UltraScale+ devices deliver the adaptability and scalability needed to meet evolving 5G O-RAN network requirements, while delivering high cost efficiency.

“As market demands for 5G continue to evolve, Fujitsu also recognizes the importance of integrating Xilinx adaptive RFSoCs to meet next-generation wireless deployment standards,” said Liam Madden, senior vice president and general manager, Wired and Wireless Group, Xilinx.

“Fujitsu’s wireless platform and Xilinx’s UltraScale+ portfolio of solutions provide the foundation for realizing the benefits of O-RAN, which is key to 5G deployments,” said Masaki Taniguchi, senior vice president and general manager of the Mobile Systems Business Unit at Fujitsu. “We will continue to work with Xilinx to integrate our RFSoC product family into next-generation solutions.”
